src/write_riemann_threshold.h: Various fixes.

* Add license header. Simply copied src/write_riemann_threadhold.c's license.
* Make header self-contained. "plugin.h" is needed for data_source_t and
  value_list_t.
* Add names to the parameters and write documentation for the only exported
  function.
